: How to tell if your DSP2 switch is working. baxterboy 10-19-2006, 01:37 AM Hello guys, I was wondering how you could tell if your DSP switch was working on (2) close tunes. Is the switching over instantly or is there a delay. I thought I would be able to tell the difference between my (2)tunes but might take a while to. epb091786 10-19-2006, 06:07 AM Its instantanious. Bentley Flashscan 10-19-2006, 07:31 AM What you could try just so you know what position is the stock and DSP2 is to lower the speed limiter on the DSP2 side to say 5MPH, go for a 'small' drive and you will soon know which one it is :) Cheers, Ross sweetdiesel 10-19-2006, 02:20 PM What you could try just so you know what position is the stock and DSP2 is to lower the speed limiter on the DSP2 side to say 5MPH, go for a 'small' drive and you will soon know which one it is :) Cheers, Ross :exactly: make sure your not be on the freeway when trying this):h Idle_Chatter 10-19-2006, 02:33 PM How about something simpler and less "dramatic" like setting the idle to 1000 rpm in the "B Tune" and then trying the swap sitting safely in Park (no fun, I know!)

No delay, unground the switch and then when the truck is keyed off use a meter to test continuity from one side to the other, Then you will know when the switch is on or off, meaning closed is DSP2 and open is the main tune.

Kennedy 10-19-2006, 10:03 PM I temporarily set TBIQ to 0 on all cells to verify switch position and function. joefarmer 10-22-2006, 04:06 AM I set A0105 DSP2 Main Injection Pulse, row 10mm3, column 10-190MPa to 1200. The truck will lope when the switch is grounded. brandon. | ||
